What Are The Roles Of Solar Charge Controllers?

The roles played by the solar charge controllers cut across all these devices.  For you know mppt solar charge controller even better it is also important for you to, first of all, make sure that you have a better understanding of this tool.  If you have no idea of what these controllers do here is some information about the same.  

1. They Prevent Overcharge 

When you are charging a battery using a solar panel and it gets full that does not mean the charge stops there.  The charge will go on and on if it is allowed which might in the end result in the damaging of the battery.  This is exactly where the solar charge controller comes in.  It prevents any potential incident of overcharging which might result in damage to your battery.  

2. It Helps In Controlling A Load 

The solar charge controller is designed in such a way that it can switch off and on the DC current.  This helps in making sure that the device needs are adequately addressed.  

3. It Helps In Blocking Reverse Current 

When solar panels have lower voltage compared to the battery then the current might actually flow backward.  This happens too in many cases and especially at night.  When such a thing happens, it might lead to a massive escape of power leaving you disadvantaged in the end.  

However, if you have a solar charge controller then you will be able to deal with this problem.  You will not have to incur the inconveniences of having to see your power sucked back to the solar.  The controller will help you to make sure that this problem is well dealt with. 

There are also other cases where solar charge controllers are used for other purposes which include turning on and off lights.  However, the use of these devices for these roles are very minimal and on very rare occasions, not always.  

Types Of Solar Charge Controllers

There are many types of solar charge controllers.  This means if you need one of these many types you are going to need to be very careful.  If you do not choose the right type then you might end up in some form of problems in the end.  

For you to make the right decision in this regard, there are some factors you need to consider when choosing a solar charge controller.  Sticking to these factors will enable you to get nothing short of the best solar charge controller from the market.  Here are some of the factors you need to consider when choosing a solar charge controller.  

The Type Of Solar Charge Controller 

There are many types of solar charge controllers but the main ones of them are the following: 

  • Shunt charge controllers 
  • PWP controllers 
  • MPPT controllers 

The Shunt Charger Controllers 

This is one of the oldest types of solar charge controllers.  Much more like its name suggests the type of controllers use the most basic concept to make sure that a battery does not overcharge.  The design of these controllers is in such a way that the current flows to the battery at the highest possible rate.  

When the battery voltage gets to a certain level of preset threshold, there is a switch that is activated within the controller.  This switch then blocks the flow of current to the battery making sure that your battery does not overcharge.  

When the voltage in the battery drops below the required threshold, the switch gets activated to make sure that there is a continuous flow of voltage to the battery.  The switch will remain on until the upper preset threshold is reached again.  

Even though the shunt solar charge controllers were very popular back in the day, they are not so common in the current times.  These controllers became somehow obsolete and have now been replaced by much better and superior controllers.  However, you can still use them especially if you are looking for a much simpler and affordable solar charge controller.  

PWM Charge Controllers 

This is one of the modern solar charge controllers there is in the market.  The PWM is an abbreviation for pulse width modulation in full.  Unlike the case of shunt controllers which cut the flow of current at once, this type of controller only reduces it.  

These kinds of controllers monitor the flow of current or voltage if you like to the battery.  As the battery gets charged to almost full capacity, the PWM controller reduces power or voltage flow to the battery.  However, much as this is the case, there is still a problem that comes with it as well.  

For it to work out then the solar battery and solar panel itself must have similar voltages. For instance, if you have a solar panel of 12 volts then you need to have a battery of either this voltage or something close to it.  Other than this, these kinds of solar charge controllers are also not designed to handle higher voltages.  This means in case of any high voltage then the controller might actually get overwhelmed and fail to deliver.  

The MPPT Charge Controllers 

This is the maximum PowerPoint Tracking.  This is the newest kind of solar charge controller in the market.  These controllers monitor the battery charging voltage rate.  When the charging goes on and the battery to almost its full capacity the controller switch comes on automatically which then reduces the current flow.  

The current flow goes down slowly until such a time when it nears its full capacity when it finally stops the flow to the battery. Doing so stops or rather prevents the battery from overcharging which helps in increasing the life of the battery.  

Therefore, if you have a solar panel as well as a battery that operates on two different voltages then this is the kind of solar charge controller you need. With this kind of controller, you will be able to deal with any problems that involve the suck back of voltage and others.  

If you are also dealing with high power and you need a tolerant solar charge controller then this is what you need to go for.  This kind of solar charge controller is designed in such a way that it can actually withstand high power voltage unlike the others which are shown in the text above.  

What You Are Your Needs 

That is it about the solar charge controllers.  If you are choosing a solar charge controller you also need to consider what your needs are.  This is also very important to note as it will help you get the best solar charge controller in the market.  

If you have high power and you feel that might actually affect your battery then better look for an MPPT charge controller.  It is the kind of solar charge controller that is designed for this kind of voltage.  With it, you will be able to handle or rather with the whole issue of power voltage control from your solar to your battery.  

Easy Of Set Up 

It is also not a bad thing for you to consider the ease of setup when choosing a solar charge controller.  You do not need something that is so complicated to set up.  Instead, you need an easier solar charge controller that you can even set up yourself.  

Thus, before you buy any it is very important for you to, first of all, consider how easy it is for you to set up the controller.  Buying a solar panel charge controller that is not so easy to set up then might cause you some problems in the end.  Better go for something that you can set up all by yourself without having to struggle a lot.  

Conclusion 

If you have to buy a solar charge controller, then listed above are some of the factors you need to consider.  These factors will help with ways on how to select a solar charge controller that will help you get the best out of your solar energy.
